This invention rela-tes to a liquid fuel burner for furnaces and the like, the general object of the invention being to provide means for adjusting the burner so as to direct the 5. flame therefrom to different parts of the furnace for the purpose of getting an even distribution of the heat in all parts thereof so as to overcome all hot and cold spots in the fire by shifting the oil spray from the burner 1.0i up or down or to either side, as is necessary.

This invention `also consists in 'certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustratedy in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying draw-` ings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevation showing the same applied to one form of furnace apparatus.

Figure 2 is a fragmentarytop view of one of the supporting brackets.

Figure 3 is a top plan view showing how a part of the burner is connected with the brackets.

Figure 4 is a sectional view throughthe 30 ball and 'socket connection shown in Figure 1.

Figure 5 is a view of the forked member which is connected with the burner.

Figure 6 is a section on the line 6 6 of 1 Figure 1.

Figure 7 is a view showing the invention applied to another form of furnace apparatus.

Figure 8 is a front view of Figure 7.

Figure 9 is a view of the support for the horizontal pipeshown in Figure 8.

Figure4 10 is a View of the rotary connection between two ofthe pipes.

In the drawings, the letter A indicates 'r the burner body the discharge end 1 of which is so locatedwith respect-to` the furna, Y

to direct the flames into said furnace andthe letter C indicates the air conduit for intro duci-ng air into the burner A, oil beingv `in-k troduced into the burner through the pipe-2. In carrying out'my invention., I attach an angle shaped bracketv 3 to jthe front ofthefurnace by the bolts 4 and the horizontal limb vof this bracket is corrugated on yits upper, face as shown at 5 andjhas an opening jtherein adjacent itsouter end. e l i )A plate 7 has itsunder face corrugated to engage the corrugated face of thebracket 3 and this plate is also formed with ay slot 8 through whichfpasses a bolt 9 which also passes through the hole 6. A nut 10 formed with. a handle 11l is threaded on the bolt to hold. the parts in adjusted position. AS shown Yin Fig. 6, the bolt' 9is held against. rotary movement Y in lthe horizontalpart of the bracket 3, but as the circular part of the bolt passes through the slot 8, in the plate 7 ,-7

for loosening thenut 10the plate 7 can y; be

partly1 lifted from the bracket 3 ,and partly turn-ed on the boltto adjust the burner body in a horizontal plane and by moving the plate 7 away from or towards the furnace the burner body can be adjusted toward and' away from the furnace. Plate 7 is Vformed with a head 12 which 'is vertically arranged and which has a slot 13arrangedqtherein, and aforked bolt ,14 isthreaded in an 11pstanding projectionl yon the` burner 59d?.

andabolt 16 passes through the upper ends oftheforks 'of the bolt and thro'ughtheY slot 13." j f From the foregoing it will be seen thatv the rburner Abody can bepadjusted toward-s and lower ory upper partof the furnace as well as Y the .Centralpart and the burner canals@,beA

adjusted vertically through means of the'bolt 16 passing through the slot 13.

V In order to permit this movement of the burner body the conduit C is formed with a spherical joint 17 which consists of a substantially spherical member 17 on the lower end of the part 18 of the yconduit fitting in a substantially spherical part 17 in the lower part of the conduit. Thus the part 17 will turn on the part 17 during the adjustment of the burner body A.

In the fo-rm of the invention shown "in Figure 7 the conduit C is formed with the rotary joint 19 which connects the elbow 2O with a nut on the bolt, said plate having a vertically arranged head at its other end having an elongated slot therein, a vertically arranged forked member connected with the body, a` bolt passing through the prongs of the fork through the slot in the head, means for introducing liquid fuel intothe body, and an air conduit in communication with the body and composed of sections, and means for movably connecting the sections together whereby adjustment of the body can be made without interference from the conduit.

In testimony whereof I aix my signature.

the vertical and horizontal parts of the conduit, one of these joints being shown in detail in Figure 10 and comprises a sleeve19 fitting over a pair of flanges 21 on the abutting ends of the two parts of the conduit when the burner body is swung about a hori zontal axis the upper end of the elbowv20 will turn in the upper joint 19 in Fig. V8 and when the burner body is turned about a vertical axis, the lower vjoint 19 will turn about ailower end of the elbow 20. f

- A bracket 22 supportsv the horizontal part of the conduit, thisbracket being shown in detail in Figure 9. Figure 7 shows in dotted lines23 how the oil spray can be directed downwardly and upwardly or in a straight line, and as before stated, the spray can also be directed to either side of the furnace or to the center thereof.

' It is 'thought from the foregoing descrip# tion that the advantages and novel features of the invention'will be readily apparent.

It is to be understood that changes may be made in thel construction and in the combination and arrangement of the several parts y extending forwardly, va plate engaging said forwardly extending part and having an elongated yslot therein, a bolt passing thru the forward part of the bracket and the slotV 1n they plate, a nut on the bolt, said plate havinga vertically arranged head at its outer end having an elongated slot therein, vertically arranged fork members connected with thebody, a bolt passing through the prongs Ofltheiforkand through the slot in the head,
